ACKNOWLEDGEMENT

I express my gratitude to HOD, Dr. Vinod Kumar Singh, Department of Electronics Engineering and Dr. Neelam Srivastva, my Seminar Guide for providing me with adequate facilities, ways and means by which I was able to complete this seminar. I express my sincere gratitude to him for his constant support and valuable suggestions without which the successful completion of this seminar would not have been possible.

I express my immense pleasure and thankfulness to all the teachers and staff of the Department of Electronics Engineering, I.E.T. LUCKNOW for their cooperation and support.

This seminar report has been benefited from the many useful comments provided to me by the numerous of my colleagous. In addition many other of my friends have checked it and have offered many suggestions and comments. Besides there are some books and some online helps.Last but not the least, I thank all others, and especially my classmates and my family members who in one way or another helped me in the successful completion of this work.

ABSTRACT

This seminar examines the new technology of Holographic Projections. It highlights the importance and need of this technology and how it represents the new wave in the future of technology and communications, the different application of the technology, the fields of life it will dramatically affect including business, education, telecommunication and healthcare. This also discusses the future of holographic technology and how it will prevail in the coming years highlighting how it will also affect and reshape many other fields of life, technologies and businesses. Holography is a diffraction-based coherent imaging technique in which a complex three-dimensional object can be reproduced from a flat, two-dimensional screen with a complex transparency representing amplitude and phase values. It is commonly agreed that real-time holography is the ne plus ultra art and science of visualizing fast temporally changing 3-D scenes. The integration of the real-time or electro- holographic principle into display technology is one of the most promising but also challenging developments for the future consumer display and TV market. Only holography allows the reconstruction of natural looking 3-D scenes, and therefore provides observers with a completely comfortable viewing experience. But to date several challenges have prevented the technology from becoming commercialized. But those obstacles are now starting to be overcome. Recently, we have developed a novel approach to real-time display holography by combining an overlapping sub-hologram technique with a tracked viewing-window technology.
